Web of Science is a Clarivate product, and users can search for journals in the Journal Master List at Clarivate (Web of Science).
We remind our readers that, while the impact factor is an important metric for journal publishers, editors, and libraries to identify leading journals, Clarivate employs extremely intransparent processes to select journals for evaluation and it takes many years (for example, 8 years for JMIR Mental Health) to be finally indexed; thus, the absence of an impact factor should not be interpreted as a journal not being influential - it may simply reflect the frustrating lack of timeliness of this metric.
Thus, for this and other reasons, we do not support misuse of the impact factor for the evaluation of individual works, researchers, or institutions (see DORA principles and What is Impact Factor misuse?).
